Questão jurídica principal
Whether the Italian request met the admissibility requirements and could be refused because its facts allegedly conflicted with the Swiss investigation
Decisão extraída
The request was sufficiently reasoned and not manifestly erroneous, incomplete, or contradictory; the cantonal authority could not refuse assistance on that basis.
Fundamentação extraída
Swiss authorities must rely on the request unless it is plainly defective; they do not conduct a full evidentiary inquiry and assistance may be used to clarify unresolved points.
